Mass Effect 3 Wiki Guide

Soldier

The Soldier is Commander Shepard's default class, which focuses on armed combat. Soldiers are pure combat specialists: no one is tougher or more suited to taking down enemies with barrages of gunfire. Soldiers have thorough weapons training and can use all special ammo types as well as grenades. High-level operatives are outfitted with ocular synaptic processors that allow them to focus on targets with lethal accuracy.

The Soldier uses the Omni-Blade as his or her heavy melee attack, pulling their arm back and thrusting it into the enemies chest, causing massive damage.
